The Clinical Significance of a 'Crazy-Paving' Pattern on Chest Radiology.

Eur J Case Rep Intern Med 2018 27;5(12):000978. Epub 2018 Dec 27.

Pulmonary Department, Loewenstein Lung Center, Löwenstein, Germany.

A crazy-paving pattern is a non-specific radiological sign which is characterized by the presence of diffuse ground-glass attenuation associated with interlobular septal thickening and intralobular lines. It was initially described as a pathognomonic sign of pulmonary alveolar proteinosis. However, it can be also found in many other diffuse acute and chronic lung diseases including diffuse alveolar haemorrhage (DAH), a rare and life-threatening clinical syndrome which can be caused by many conditions, the most frequent of these being capillaritis associated with systemic autoimmune diseases.

Ter Arkh 2018 May;90(5):13-22

V.A. Nasonova Scientific Research Institute of Rheumatology, Moscow, Russia.

Antineutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV) are rare autoimmune disorders and characterized by severe multiple organ lesions with a potential fatal outcome. AAV comprises granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA). Early diagnosis and treatment can significantly improve the AAV prognosis, but there are can be difficult, largely due to the lack of criteria for the classification MPA, whose main difference is the absence of granulomatous inflammation.

Antineutrophil Cytoplasmic Antibody-Associated Vasculitis in Korea: A Narrative Review.

Yonsei Med J 2019 Jan;60(1):10-21

Division of Rheumatology, Department of Internal Medicine, and Institute for Immunology and Immunological Diseases, Yonsei University College of Medicine, Seoul, Korea.

Antineutrophil cytoplasmic antibody-associated vasculitis (AAV) is a group of systemic necrotising vasculitides, which often involve small vessels, and which lead to few or no immune deposits in affected organs. According to clinical manifestations and pathological features, AAV is classified into three variants: microscopic polyangiitis, granulomatosis with polyangiitis (GPA), and eosinophilic GPA. The American College of Rheumatology 1990 criteria contributed to the classification of AAV, although currently the algorithm suggested by the European Medicines Agency in 2007 and the Chapel Hill Consensus Conference Nomenclature of Vasculitides proposed in 2012 have encouraged physicians to classify AAV patients properly.

Alveolar Hemorrhage in Vasculitis (Primary and Secondary).

Semin Respir Crit Care Med 2018 08 7;39(4):482-493. Epub 2018 Nov 7.

Department of Respiratory Medicine, Hospices Civils de Lyon, National Reference Center for Rare Pulmonary Diseases, Lyon, France.

Defined by the accumulation of red blood cells into the alveolar space, diffuse alveolar hemorrhage (DAH) is a severe and potentially fatal medical condition requiring careful attention. In contrast to simple extravasation of erythrocytes facilitated by impaired hemostasis or hemodynamic causes, DAH in vasculitis is due to capillaritis, that is, inflammation of capillaries. Dyspnea, hemoptysis, chest infiltrates, and abrupt fall of blood hemoglobin level represent the cardinal features of DAH; yet, hemoptysis is lacking in one-third of cases. Read More

Microscopic polyangiitis (MPA) is one of the main clinical presentations of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides. Although the disease is defined by clinical and pathological criteria, the anti-myeloperoxidase (MPO) specificity of ANCAs is observed in almost 80% of MPA patients. The direct pathogenic role of anti-MPO antibodies has been proven in animal models, in which the disease was transmitted by transfer of anti-MPO antibodies or anti-MPO-specific splenocytes.

Vasculitides are a heterogeneous group of disorders in which inflammation of blood vessel walls is present at least some time during the course of the disease. Vasculitides can affect any caliber or type of vessel in many anatomic sites; however, the disease can alter more than just vasculature. Given the diversity of vasculitides, in 2012, a revised classification system was proposed to categorize vasculitides by the type of vessel involved including size, function, and structural attributes.

Pathogenesis of ANCA-Associated Pulmonary Vasculitis.

Semin Respir Crit Care Med 2018 08 7;39(4):413-424. Epub 2018 Nov 7.

University of North Carolina Kidney Center, Chapel Hill, North Carolina.

Antineutrophil cytoplasmic antibodies (ANCAs) are autoantibodies specific for antigens located in the cytoplasmic granules of neutrophils and lysosomes of monocytes. ANCAs are associated with a spectrum of necrotizing vasculitis that includes granulomatosis with polyangiitis, microscopic polyangiitis, and eosinophilic granulomatosis with polyangiitis. Pulmonary vasculitis and related extravascular inflammation and fibrosis are frequent components of ANCA vasculitis. Read More

Immune-Mediated Systemic Vasculitis as the Proposed Cause of Sudden-Onset Sensorineural Hearing Loss following Lassa Virus Exposure in Cynomolgus Macaques.

MBio 2018 10 30;9(5). Epub 2018 Oct 30.

Office of the Chief Scientists, U.S. Army Medical Research Institute of Infectious Diseases, Fort Detrick, Frederick, Maryland, USA

Lassa virus (LASV) causes a severe, often fatal hemorrhagic disease in regions in Africa where the disease is endemic, and approximately 30% of patients develop sudden-onset sensorineural hearing loss after recovering from acute disease. The causal mechanism of hearing loss in LASV-infected patients remains elusive. Here, we report findings after closely examining the chronic disease experienced by surviving macaques assigned to LASV exposure control groups in two different studies. Read More

[Vasculitides and eosinophilic pulmonary diseases].

Z Rheumatol 2018 Dec;77(10):907-922

Abt. für Rheumatologie, Immunologie und Rehabilitation, Kantonsspital St. Gallen, St. Gallen, Schweiz.

Eosinophilic granulocytes form peripheral effector cells controlled by Th2 lymphocytes, which cause local cell, tissue, and functional disorders of infiltrated organs via the release of cytotoxic basic proteins and oxygen radicals. Diseases associated with eosinophilia include systemic and organ-related forms. The lungs are involved in eosinophilic granulomatosis with polyangiitis (EGPA, formerly known as Churg-Strauss syndrome), acute and chronic eosinophilic pneumonia, as well as in an organ manifestation in hypereosinophilic syndrome and certain parasitic diseases.

antineutrophil cytoplasmic antibody-associated vasculitis in pregnancy: a systematic review on maternal, pregnancy and fetal outcomes.

Clin Kidney J 2018 Oct 15;11(5):659-666. Epub 2018 Mar 15.

Division of Nephrology, Department of Medicine, Queen's University, Kingston, ON, Canada.

Background: antineutrophil cytoplasmic antibody-associated vasculitis typically arises in post-reproductive years, but can occur during pregnancy. Concerns of treatment-related teratogenicity persist, while efficacy and safety of new therapies including intravenous immunoglobulin (IVIG) and rituximab are uncertain. There remains a paucity of maternal, fetal and pregnancy outcome data in these women, and therefore a lack of guidance on safe treatment for clinicians. Read More
